Tomography
Tomography is an imaging technique that combines projections taken from different directions into a reconstruction of the interior of a patient or an object. The ASTRA research group (“All Scales Tomographic Reconstruction Antwerp”) of imec-Vision Lab develops tomographic reconstruction algorithms for electron, X-ray, neutron, and magnetic resonance imaging. The ASTRA group developed the ASTRA-Toolbox, which is an open source, GPU accelerated software platform for the development of novel tomographic reconstruction methods; it can be downloaded from www.astra-toolbox.com.
Key expertises:
- Phase contrast X-ray CT (edge illumination and grating based interferometry)
- X-ray tomography for non-standard acquisition geometries (e.g. conveyor belt, laminography, tomosynthesis, 4DCT, ...)
- THz tomography
- Atom probe tomography
- Electron tomography
- Electrical Impedance tomography
